This August 2016 episode of Science Friday features a lively discussion between three educators on a number of questions relating to K-12 mathematics education. What mathematics skills should be taught in K-12 schools? How should these skills be taught? Should all students take the same mathematics courses? And what mathematical skills and concepts do students really need in the so-called "real world"? Participating in this discussion are political science professor Andrew Hacker, author of The Math Myth and Other STEM Delusions; Maria Droujkova, a mathematics curriculum developer and founder of Natural Math; and Pamela Weber Harris, author of Building Powerful Numeracy for Middle and High School Students. Hacker, Droujkova, and Harris have diverse perspectives on the aforementioned questions and share a number of interesting insights. This engaging discussion will be of interest to not only mathematics educators, but also to parents, guardians, and anyone with memories of their own mathematics education.
